The surface of the filter UV quartz tube is colorless or slightly blue, and its cross section is pale blue. Ce(Cerium) and other micronutrients are added to quartz to effectively block uv-b and uv-c radiation and most uv-a radiation.It can remove the ultraviolet light of 190nm-320nm wavelength in the ultraviolet spectrum, and effectively prevent the biological damage caused by ultraviolet light.

   Therefore, filter ultraviolet lamp can effecively prevent the harm to the skin of people and objects that have to be under the explosion of UV radiation and set out the maximum visible light at the same time.Filter ultraviolet quartz tube mainly used in the production of environment-friendly electric light source, which is an ideal material for quartz halogen lamp, gas discharge lamp,high density discharge lamps and UV light source.
